Epoxy Injection Preparation Tips

Introduction:

Epoxy injection is a highly effective, polymer delivery method through a pumping system for repairing cracks in concrete structures. This process involves sealing all accessible sides of a crack and bonding them with a high and strength, low-viscosity epoxy resin by pressure injection.

Proper preparation is crucial for successful epoxy injection. It begins with cleaning the crack thoroughly, surface sealing the crack, and installing surface mount Tri-Base ports along the crack at specific intervals with a fast setting, non-sag epoxy paste. Following these preparation steps ensures the epoxy resin can penetrate and bond the cracked concrete effectively, restoring its structural integrity in the process.

Epoxy Injection Preparation Tips – Installing Surface Mount Tri-Base Ports

Epoxy Injection is a typically a low pressure to medium pressure crack filling solution where all sides of the crack are sealed and structurally glued together with a high strength low viscosity Epoxy Resin.

To prep for injection, the crack must be cleaned with a wire brush and all dust removed. Any surface contaminants, such as oils or paints, must be removed for the epoxy paste-over to bond properly. If available, use clean compressed air to remove any dust and debris. For best results perform epoxy injection preparation when the crack and surface are dry. Any water seeping from the crack should be stopped prior to epoxy injection. For sealing water bearing cracks click here.

Once the surface is cleaned, the Surface Mount Epoxy Injection Ports are installed directly over the crack 6” – 8” (15-20 cm) apart. The finer the crack, the narrower the spacing should be.

Shown in this example are standard surface mounted Tri-Base ports, however corner ports and ½” drill in ports are available for specific applications.

Tri-Base Ports are mounted by placing epoxy on each of the three tabs on the base of the port. Once ports are placed, the non-sag paste is applied to both sides of the wall, sealing the crack.

When applying paste, the mixed material should be applied generously at roughly 1/8” (3-4 mm) thickness, and mounded up around each port to approximately 1/4″ (6-7 mm) thick or more using a putty knife or other suitable tool. The paste-over should be a minimum of 1 inch (3 cm) wide along the crack. If the paste is not applied thick enough it may crack and epoxy will escape during injection, preventing proper penetration and epoxy flow within the crack itself. Note: The length of time needed for the epoxy paste to fully cure varies with ambient and substrate temperature.

After the surface paste has hardened, structural strength epoxy resin can be injected starting at the lowest port on the crack, for horizontal or lateral cracks start on one side and work your way over.

Because the crack has been sealed on both sides, the next port in line will need to have the cap removed to allow the displaced air to escape. Once the Epoxy resin can be seen escaping from that next port injection stops, the applicator is disconnected from the injected port and the port is capped.

The applicator is then connected to the next port and the process is repeated. Once the crack has been fully injected and the Epoxy resin has cured, ports and paste can be ground off for aesthetics.

Epoxy does not Flow as Expected – Troubleshooter

Injected crack is not continuous or the area being injected is saturated
Crack is blocked by debris or cured epoxy paste
Surface mount port does not align with the crack
Epoxy has cured in injection nozzle, port or crack
Epoxy resin viscosity too high

Epoxy injection is an efficient and economical method of repairing cracks in structural concrete walls, slabs, columns and piers. If applied in compliance with all recommendations and specifications, high strength epoxy is capable of restoring concrete structures to their strength prior to crack development.

How to Fix Foundation Cracks

Popular Mechanics – Pop Mech Pro, Publishes Article with Detailed Pictures about “How to Fix Foundation Cracks”, using the SealBoss Crack Repair Method with Specialized Leak-Sealant and Injection Packers:

Concrete cracks have been an issue since the beginning of concrete construction three millennia ago. The article explains that modern concrete lacks self-healing properties, which causes cracks to worsen over time and impacts both homeowners and engineers.

Popular Mechanics’ century-old building in Easton, Pennsylvania, suffered from cracked concrete until local contractor repaired it. They used a specialized leak-sealant from SealBoss and ordinary tools to fill and seal the cracks, preventing further water entry and degradation.

The article discusses the SealBoss 1510 Water Stop Foam solution for fixing concrete cracks, a common issue affecting many structures from homes to bridges.

The article highlights how modern concrete deteriorates over time due to water seepage through cracks.

“After the water-stopping material has hardened into a plastic foam, the contractors removed it from the wall and floor with putty knives and scrapers. They removed the packer with a socket and socket wrench, then filled the remaining hole with mortar. With that, the job is complete.”

— Popular Mechanics, Roy Berendsohn

The solution presented in this article and involves a straightforward repair method demonstrated by the contractor, using ordinary tools and SealBoss 1510 specialized leak-sealant from SealBoss. The process includes drilling holes along the crack, inserting injection ports, and injecting an expanding liquid polyurethane resin mixed with an accelerator to seal the crack effectively.

This method has proven successful in preventing further leaks through the foundation of the century-old building occupied by Popular Mechanics in Easton, Pennsylvania, showcasing its effectiveness in concrete crack repair.

“We were amazed at the simplicity of the process and the good results it produced–we haven’t seen any further leaks through the foundation since the two men completed their work.”

Parking Garage Crack Injection

Structural and Leak Sealing Repairs

Introduction:

For effective and long term parking garage crack injection repair, the use of specific injection products for waterproofing and structural crack repair is pivotal.

For leak sealing, polyurethane foam resins, hydrophilic gels, and acrylate / acrylic gels are commonly employed. These resins, when injected, either react with water to form a foam that expands or create a gel product respectively, filling voids and sealing against further water ingress. This method not only prevents water penetration but also adds to the structural integrity of the parking facility.

On the other hand, for structural strength crack injection, epoxy resins are predominantly used. These resins are known for their high-strength bonding capabilities, effectively sealing cracks and restoring the concrete’s original strength. Epoxy resins are particularly advantageous in load bearing environments, providing strength and restoring the concrete’s structural integrity.

Both types of injection product groups are crucial in extending the lifespan of parking structures, ensuring they remain safe and functional for daily use.

Parking Garage Crack Injection Technology

For over three decades, SealBoss Crack Injection Systems have been at the forefront of providing effective solutions for structural repairs and sealing leaks in cracks and joints within parking garage structures. These systems have proven successful in not only preventing water ingress but also in preserving the integrity and functionality of parking facilities.

How to Seal Leaks in Voids, Cracks, Joints, and Seal Around Beams

In a technical support role for a leading infrastructure repair company, the job often involves providing assistance to clients on a wide array of repair projects. These projects range across a diverse spectrum, including concrete repair, waterproofing, slab lifting, soil stabilization, and permeation grouting.

Recently, there was an instance of providing consultation to a contractor. The focus was on addressing water leaks by injecting materials into voids, cracks, joints, and beam pockets that had previously been treated with mastic grout.

How To Podcast:
Leak Sealing Polyurethane Crack Injection
in Concrete and Shotcrete Structures

The area where the leaks persisted were directly below the sidewalk where the concrete meets the asphalt driveway. After inspecting the above ground conditions closely it was determined that the main source of the water intrusion were gutter downspouts. There were no drains installed to manage the directional flow of rainwater away from the structure.

Now that the source and path of water ingression had been established, polyurethane pressure injection of the affected areas was confirmed to be the correct solution to seal the leaks.

The first areas that needed to be sealed were leaking beam pockets which had been previously filled with a mastic patch grout. Over a 30 year period there had been multiple previous attempts by various contractors to repair the leaking areas. No records were available on the various works that had been performed.

It was decided to inject through the wall to the back side of the structure to cut off any water before it could find its way into the beam pockets. This method combines void fill and permeation grouting as product is injected beyond the structure into a space that in this instance is confined by concrete / steel, asphalt and dirt. As the foam disperses under pressure injection and during expansion, it partially migrates / permeates also into the dirt further enhancing the ability to seal the void.

Using two strategically placed SealBoss Evolution 13-100 AL packers, the contractor injected 1510 Water Stop Foam, catalyzed with 10% 15x Accelerator, at several intervals, permitting the resin to expand to a dense foam creating a seal and protecting the beam pocket from any water intrusion from behind the wall.

The injection process was monitored from the inside and outside and the contractor stopped injection once air bubbles and water were observed coming up through the asphalt driveway. Expanding foam displaced water in the affected area. Injection was continued at a slow rate until water displacement finished and increasing resistance indicated full penetration.

Next, the contractor injected all visible and leaking cracks some of which at one point had been injected with a structural / rigid epoxy which had failed. Reason of epoxy failure was determined as either lack of bond due to actively leaking cracks during epoxy injection and/or failure due to crack movement such as contraction and expansion. Polyurethane injection is the preferred method to address actively leaking and water bearing cracks, especially in areas where structural repairs are not necessary. The two foot thick wall was injected with 1510 leak-seal foam in intervals till the crack showed refusal of the resin.

Cold Joint Injection

Leaking Cold Joints Sealed

Cold Joints in Concrete Structures and the Polyurethane Polymer Solution

Introduction

Concrete is a versatile and durable construction material, but like all materials, it has its weaknesses. One such weaknesses is the formation of cold joints. Understanding what cold joints are and how to address them is crucial for anyone involved in the construction or repair of concrete structures.

What are Cold Joints?

A cold joint forms when newly mixed concrete is laid adjacent to or over concrete that’s already started to harden. This situation can manifest due to several factors, including disruptions during pouring or delays in the mixing and transportation of the concrete. This leads to the formation of a distinct boundary, a zone lacking cohesion, where the previously set and fresh concrete converge. Such a boundary weakens the overall structural strength of the concrete, rendering it susceptible to water infiltration and potential leakage. Over time, the presence of cold joints can reduce the overall lifespan of the concrete structure.

The Polyurethane Polymer Foam Injection Solution – Injecting cold joints with polyurethane polymers has emerged as an effective solution to address the issues of water migration and leakage.

Injection Process

Using specialized equipment, the polyurethane polymer is injected into the cold joint. The polymer fills the voids and gaps, creating a permanent seal. The polymer acts as a barrier, preventing water from seeping through the cold joint. The injected polymer reinforces the cold joint, reducing the risk of corrosion, cracks or breaks. With the cold joint addressed, the overall lifespan of the concrete structure can be significantly extended.

Addressing Cold Joints with the SealBoss Injection System – Comprehensive Solution to Moisture and Active Leaks

Cold Joints are common locations where moisture and active leaks are frequently observed. Whether stemming from a flawed waterproofing system or its total absence, we offer a comprehensive solution to address the leak and stop any water intrusion.

Our SealBoss Regional Sales Manager was on-site in Kansas City to train and assist with the injection of below grade cold joints that had begun to actively leak due to failures in the pre-existing waterproofing system.

Both vertical and horizontal cold joints were injected with various levels of leak activity. The contractor drilled the injection holes and installed 1/2″ SealBoss mechanical packers for a tight fit. Based on the conditions the 45 angle drill degree method was used as well a direct into the joint placement was chosen.

The applicator then injected SealBoss 1510 using the P2002 high-pressure single component injection pump. Due to the relatively low temperatures of the substrate the product was catalyzed with approximately 15% of SealBoss 15X highfoamer accelerator. All active leaks were successfully stopped and the Cold Joints sealed.

SealBoss Leak Sealing Foam injection is an effective solution, sealing cracks and joints to create a watertight barrier. This article details a case study using this method to permanently fix basement leaks, offering a reliable approach for homeowners and contractors.

How to Fix a Leaky Basement

Water damage is a serious issue that can have devastating effects on your home. Not only does it decrease the value and livability of your property, but it can also compromise the structural integrity of your home. A leaky, damp basement is particularly concerning, as it creates a breeding ground for harmful mold and bacteria that can cause health issues for you and your family.

In addition, a damp basement can attract pests such as termites and rodents, causing further damage and infestations. It’s crucial to address any water damage in your basement as soon as possible to avoid these issues and prevent them from escalating. With the right tools and procedures, you can successfully mitigate basement leaks and protect your home from further damage.

Cracks and Cold Joints are Known Areas for Basement Leaks to Occur

Unsealed cracks and cold joints in your basement, or any below grade spaces, can be a major source of water damage, as they provide an easy pathway for water to enter your home. This can result in flooding, which not only damages your belongings but also compromises the structural integrity of your home. In addition to damaging walls, coverings, furniture, and storage items, water can also cause electrical hazards and increase the risk of fires.

Common Causes for Concrete Foundation Leaks and Wall Cracks

Concrete wall cracks, especially in basements, can be caused by a variety of factors that compromise the integrity of the structure and allow water intrusion. Here are some common causes:

Inadequate Construction
– Insufficient Material Quality: Using substandard materials or improper mixing ratios can weaken the concrete, making it more prone to cracking.
– Poor Waterproofing: In new homes, improper waterproofing techniques can lead to leaks and cracks.
Deteriorating and Stressed Concrete
– General Wear and Tear: Over years, concrete naturally deteriorates due to environmental factors, resulting in the formation of cracks.
– Thermal Expansion and Contraction: Exposure to repeated cycles of heating and cooling causes concrete to expand and contract, leading to cracks over time.
Soil Related Problems
– Low Compaction and Consolidation: Inadequately compacted soil beneath the foundation can shift, leading to structural instability.
– Erosion: Water erosion can wash away the soil supporting the foundation, causing it to settle unevenly and crack.
– Freeze/Thaw Cycles: Water in the soil can freeze and expand during cold weather, then thaw and contract in warmer conditions. This cycle exerts pressure on the foundation, causing it to crack.

How do I Stop my Basement from Leaking?

There are many methods to mitigate basement leaks. The construction of the basement and environmental factors have to be considered when choosing the right products and procedures, and it is always advised to consult a professional in the process.

One solution that has been successfully used for over thirty years is the SealBoss Leak Sealing Foam injection system. This system seals leaking basement cracks and cold joints by injecting a foam that expands to fill and seal the gaps, creating a watertight barrier. This method is effective, long-lasting, and cost-efficient, making it a popular choice for homeowners and contractors alike.

Leaky Basement Repair – Joint and Void Filling Injection

Scope

A homeowner faced persistent basement leakage through cold joints where the wall meets the floor.

Previous repair attempts by a contractor using crystalline products and epoxy coatings had failed, resulting in water pooling on the floor after heavy rains.

In search of a permanent solution, the homeowner sought to prevent further water intrusion into the basement.

Leaky Basement Repair – Detail

A SealBoss technical representative was called to provide expertise on sealing the basement leaks.

Upon careful examination of the job site, it was discovered that the basement floor was approximately 8 inches thick and was poured slightly deeper towards the walls. The source of the leakage was identified as the cold joint between the wall and the poured slab.

Repair System

SealBoss 1510 Water Stop Foam was chosen as the preferred leak sealing injection product to provide a permanent solution. The product would be injected through SealBoss injection packers using the SealBoss P2002 injection machine, a compact, lightweight, and quiet pump ideal for this application.

Procedure

1. Drilling the Slab

The slab was drilled with half-inch holes spaced one foot apart, parallel to the wall, and ten inches from the wall.
The holes were drilled at a 90-degree angle and full depth into the slab.
After drilling each hole, the presence of heavy substrate saturation along the wall was confirmed by water filling the hole, indicating a void beneath the slab that needed to be filled with foam during the injection process.

2. Setting the Packers

- Once all the holes were drilled, packers were placed at half depth and only hand-tightened for easy removal during injection.

- The injection process began on the side closest to the crawl space’s stub foundation wall.
- The first packer was loosened, placed at full depth, and retightened, while the next packer in line was removed to allow for a path of less resistance for any displaced water or soil to escape from below and provided visibility for material travel.

3. Injection Process:

- Each packer was injected until catalyzed foam was observed coming out of the adjacent hole.
- The packer was reinjected a second or third time until refusal or sufficient pressure buildup.

Leaky Basement Repair – Conclusion

This combined joint injection and void filling injection procedure proved to be the most effective method for sealing the basement leaks

efficiently and permanently. The use of SealBoss 1510 Water Stop Foam, along with precise drilling and injection techniques, ensured that the cold joints and voids were thoroughly sealed, providing a lasting solution to prevent water intrusion.

Additional Tips for Homeowners and Contractors

Regular Inspection:
Periodically inspect basements, especially after heavy rains, to detect early signs of leakage.
Proper Drainage:
Ensure proper exterior drainage systems, such as gutters and downspouts, are in place to divert water away from the foundation.
Professional Consultation:
Consult with experienced professionals for thorough assessments and tailored solutions for basement waterproofing.

By following these steps and employing advanced sealing techniques, homeowners and contractors can effectively address and prevent basement leakage, ensuring a dry and secure living space.

Hydrophobic versus Hydrophilic Polyurethanes

Hydrophobic vs Hydrophilic Polyurethanes

Injection Foams, Resins and Gels

Introduction

Dive into the technical distinctions between hydrophobic and hydrophilic polyurethanes. These two types of polyurethane chemical injection grouts exhibit unique behaviors with water—hydrophobic resins repel water, whereas hydrophilic resins absorb it. This key difference informs their use in various concrete repair and sealing applications. Our guide provides a straightforward comparison to help you select the appropriate material based on the specific requirements of your project.

Hydrophobic versus Hydrophilic Polyurethanes and Acrylic Chemical Grouts Explained

Polyurethane chemical injection grouts can be broadly categorized into two types: hydrophobic and hydrophilic.

The primary distinction between hydrophobic and hydrophilic polyurethane resins designed for injection lies in their interaction with water. Hydrophobic injection resins repel most of the water, whereas hydrophilic injection resins absorb it during their reaction.

Both hydrophobic and hydrophilic injection resins, despite their varied reactions to water, can be highly effective for sealing and repairing gaps, cavities, and leaks in concrete structures. However, choosing one over the other is not arbitrary, it largely depends on the specifics of the application and the nature of the issue that needs addressing.

Thus, by understanding the distinct properties of each material, one can determine the best fit for a given situation and application.

Hydrophobic Polyurethanes

The term “hydrophobic” comes from the Greek words “hydro” meaning water and “phobia” meaning fear, resulting in a material that repels water. In the case of hydrophobic grouts, they have little tendency to absorb water into their structure.

Hydrophobic, water-activated polyurethane foams , also known as water blown polyurethanes, need just a tiny amount of water to set off the reaction, leading to polymerization and expansion. During the process of polymerization, a small proportion of water interacts with the polyurethane resin, which produces carbon dioxide gas. This gas expands the foam, leading to the creation of a compression seal in a confined space. Any surplus water is forced out during this process.

After curing, hydrophobic foam grouts maintain their shape, size, and volume without being affected by dry cycles within the substrate. Hydrophobic grouts, once cured, produce a foam of varying rigidity and flexibility. Their high foaming property allows for significant expansion in volume, filling large voids with minimal material. This expansion can reach up to 40 times the initial volume.

Single Component Hydrophobic Water Stop Foams
Water stop and leak-sealing foam grouts are usually available as a single component material, along with an accelerator that can regulate expansion rates, induction, and cure times. These hydroactive hydrophobic foams share similar characteristics. The reaction is initiated only by water or moisture, but once cured, the product remains unaffected by moisture and maintains a constant volume. Since water is not part of the foam structure, the cured material is not affected by water or dryness and does not shrink or swell. These products are also not affected by freeze/thaw and wet/dry cycles.

Characteristics
Cured Product: Rigid, Semi-Rigid, Flexible Foam
Reactive Mechanism: Requires Moisture / Water
Accelerator Adjusted: Yes
Elongation Properties: Up to 250%
Wet/Dry Cycles: Essentially Not Affected
Adhesive Bond to Substrate: Good
Application Equipment: Single Component

Hydrophilic Polyurethanes and Acrylics (Acrylates)

The term “hydrophilic” comes from the Greek words “hydro” meaning water and “philia” meaning love, referring to a material that readily absorbs water into its structure and can form gels. Hydrophilic grouts absorb water molecules during the reaction and polymerization, resulting in a highly flexible product.

These grouts can accommodate movement during expansion and contraction cycles. While hydrophilic grouts may dehydrate and shrink to some extent based on the amount of water absorbed, in most applications and environments, the surrounding concrete or soil’s moisture content and humidity are typically high enough to keep shrinkage to a minimum. Hydrophilic resins can achieve excellent bonding with wet concrete as they penetrate deeply into the pores and hairline cracks.

Single Component Hydrophilic Foam /Gel
Water initiates reaction and either forms a foam or gel based on water absorption. The product is capable of absorbing and incorporating water post cure, thereby swelling and forming a waterproofing flexible gel or foam.

Does FlexGel Hydrophilic Resin Shrink in the Absence of Water when used for Crack Injection?
When used as a single component injection grout, and without water mixed into the product prior to crack injection, FlexgGel will reject excess water similar to a hydrophobic polyurethane foam grout – resulting in a cured product of low water content. FlexGel Injection Rubber product will perform in line with the hydrophobic grouts. Please refer to data sheet for details.
